10–20HP LRST Series Tank Mounted, Direct Drive Screw Air Compressor
Variable-Speed Efficiency, Now Within Reach of Smaller Air Users
The Anest Iwata LRST Series is the newest addition to its screw compressor line-up, built around a permanent magnet motor and 1:1 direct drive. Where variable-speed, energy-saving technology was once practical only for large-scale air users, the 10–20HP LRST range brings that same efficiency to small and medium operations — particularly those with fluctuating air demand that want a compressor able to scale output with actual usage rather than run at a fixed speed regardless of load.
Oversized rotors, a bearing-free motor design, and an IE4-rated permanent magnet motor combine to push efficiency higher while keeping wear to a minimum. Triple lip shaft seals keep the system leak-free, and the oil-cooled IP65 motor runs quietly at just 68dB — making the LRST tank-mounted range as suited to noise-sensitive settings as it is to standard industrial floors.

FAQ
Who is the LRST Series best suited for?
It's designed for small to medium air users with variable air demand, or anyone who wants an energy-efficient compressor that scales output with usage technology that was previously only cost-effective for large-scale operations.
How does the permanent magnet motor improve efficiency?
The IE4-rated permanent magnet motor, paired with 1:1 direct drive, delivers the highest level of motor efficiency available in this class, cutting energy consumption compared to standard induction motors.
How quiet is the LRST Series in operation?
It runs at approximately 68dB, making it suitable for noise-sensitive environments where a standard industrial compressor might be too loud.
What keeps the LRST range low-maintenance over time?
A bearing-free motor design, low rotational speed, and triple lip shaft seals all work together to reduce wear and prevent leaks, keeping the compressor reliable with less frequent servicing.
Why are oversized rotors significant in this range?
The large, oversized rotors increase overall efficiency by up to 60%, allowing the compressor to deliver more air output per unit of energy consumed.
